摘要： An object of the invention is to reduce the size and weight of a video projector by shortening the length of the arm of a mirror rotator and reducing the size of a mirror. A video projector comprises a plurality of projection lenses through which image light rays from a liquid crystal panel are extracted in a magnified manner; a reflective mirror for reflecting the extracted image light rays onto a screen; and a mirror rotator for rotating the reflective mirror so that the extracted image light rays can be reflected in particular directions. Among the projection lenses, some of the projection lenses located farther away from the liquid crystal penal are partially cut such that areas through which the image light rays do not pass are cut off to create a lens cut-off space. The mirror rotator is placed in the lens cut-off space.
